stuck in reboot after trying to upgrade os monterey
My iMac does not reboot anymore after I was trying to upgrade to osMonterey. I have tried all the usual suggestions . Safe mode does not work either. It starts to reboot, stops, 1 chime and turns off...a few seconds later 1 chime turns on and tries to reboot, same thing over and over again. Help! What can I do? Nothing I tried works. It is an old iMac but I do not want to replace it because I hardly use it. I have all my other apple devices that I constantly use but not the iMac. Still I need it to work!
I actually can't believe that I am frequently asked to update and when I finally do nothing works anymore.
iMac 21.5″, macOS 10.13
